"I want to congratulate them on their 10-year anniversary. I looked it up, the traditional 10-year anniversary is either tin or aluminum," Ellen -- who first introduced Karla to her audience in 2015 -- says. "Since it's every other day it looks like another Kardashian is getting pregnant, I got them something."

Ellen then has a crib come out made entirely of soda cans. "That took forever to make so they'll have to share that," she quips. "The best part is when the baby outgrows that, they can recycle it and make, like, $6.50 or something like that."

Kylie Jenner, Khloe Kardashian and Kim Kardashian West all have babies on the way, sources tell ET. In the latest KUWTK promo, Kim finally opened up about her and Kanye West expecting their third child via surrogate.
